The following equation is one way to prepare oxygen in a lab. 2KClO3 → 2KCl + 3O2 Molar mass Info: MM O2 = 32 g/mol MM KCl = 74
Alex73 [517]
From  the  equation  above   the  reacting   ratio  of  KClO3   to  O2  is  2:3 therefore  the  number  of  moles  of  oxygen  produced  is  ( 4 x3)/2 =  6 moles  since   four  moles  of  KClO3  was  consumed
mass=relative  formula mass  x  number  of  moles
That  is   32g/mol x 6  moles  =192grams

Which of these elements have the same number of valance electrons
solmaris [256]
Both carbon and lead belong to Group IV elements, and thus they have the same number of valence electrons. 
<span>In each of the other options, the two elements belong to different groups, and thus they do NOT have the same number of valence electrons.

I hope this helped you, please tell me if I am correct or not <3

The ratio of carbon atoms to hydrogen atoms to oxygen atoms in a molecule of dicyclohexyl maleate is 4 to 6 to 1. what is its mo
Semenov [28]
Knowing the ratio between atoms we can write an empirical formula: 

<span>C4H6O </span>

<span>we compute the molar mass of this single formula: </span>
<span>4x12 + 6 x 1 + 16 x1 = 70 g / mol </span>

<span>Now, as we know the actual molar mas being 280 g/mol, we divide this number by 70 and we get the ratio between empirical formula and molecular actual formula: </span>

<span>280 / 70 = 4 </span>

<span>This means that actual molecular formula is: </span>

<span>(C4H6O)4 or </span>

<span>C16H24O4 </span>
